EDWARD J. MORRIS, OF SYRACUSE, NEW YORK, ASSIGNOR. OF ONE-HALF TO ANDREWJ. L. PENDERGAST, OF SYRACUSE, NEW YORK.

CAN-HEADIN G MACHINE.

T o all whom it may concern:

le it known that. I, EDWARD J. Mouais. of Syracuseyin the county ofOnondaga, in the State of New York, have invented new and usefulimprovements in Can-Heading Machines, of which the following, taken inconnection with the accompanying drawings, is a full, clear, andexact/description.

This invention relates to certain improvements in can heading machinesfor crimping the marginal edges of the heads upon the ends of tin cansin such manner as to form an air tight joint and hermetically seal thecans without the use of solder at such joints. l

The mai-n body of the can is first made up in cylindrical form and itsends provided with outwardly projecting annular flanges, while the headsare of somewhat greater diameter than that of the end ianges on thecans, the central portions being slightly cupshape to fit into the endof the can, and the marginal ed e is turned inwardly to form an annularange surrounding that of the end of the can when the head is placed inposition for crimping.

One of the oluects of my invention is to I)rovide a simple and moreeffective means or gradually but expeditiously crimping the marginalflange of the head over and upon that of the end of the can in suchmanner as to form a double fold or lap and at the same time to firmlypress all parts of the flanges into close interlocking engagement witheach other to make an absolutely air tight joint and therebyhermetically seal the can. This is accomp ished through the medium of anon-rotatable axially movable presser head for engaging and holding thehead of thecan against turning, and ,a `coaxial rotary axially movablehead carrying suitable crimping rollers which are brought into`engagement with the flangegof the can head and then drawn inwardlytoward each other under a rolling motion to overturn the marginal edgeof the can head u on the end flange of the can; and another' o ject ofmy invention is to provide means controlled by the operator whereby therotary head ay be .rotated independently of the presrslre head and alsoindependently of the mechanism by which it is moved axially.

One of the specifieobjects is to mount the crimping rollers in pairsupon separate rock Specification of Letters Patent.

Application led Mag,- 15.

arms and to draw the rollers of one pair inwardly by the axial movement4of the rotary head upon wh ich said rock arms are mounted.

Another specific object is to canse one pair ot rollers to be drawninwardly sliglitly in advance of the other p-.iir ot rollers topartially crimp thc edges of thtx can head while the second set. ofrollers complete the crimping operation.

Other objects and uses relating to specific parts of the machine will`bcbrought out in the following description.

YIn the drawings 1-Figure 1 is a vertical sectional view partly inelevation of a machine embodying the various features of my invention.Figs. 2 and 3 are enlargedf'horizontal sectional views takenrespectively on lines 2 2 and 3 3, Fig. 1, showing particularly therevolving head, portions of said head being broken away in Fig. 3 toshow the underlying crank arms. Fig. l is an i enlarged elevation of theheads shown in Fig. l in operative position upon the head of a can. thelower portion of the non-rotatable head being shown in section. Fig. 5is a vertical sectional view taken on line 5-5, Fig. 4, the shaft beingshown in elevation. Figs. G and 7 are enlarged detail sectional views ofone end of the can showing the can head uncrimped in Fig. 6 and crimpedin Fig. 7.

The can, as 1-, is plat-cd by hand or otherwise lupon a suitable shelfor support 1- forming a part of the main supporting frame HZ of themachine, at'ter which the head of the can, as JJ- is placed by hand orotherwise upon the upper open end of the can ready to be crimpedthereon, thc end of lthe cylindrical main body of the can being providedwith an outwardly projecting annular flange -rL-, with which themarginal edge of the can head -bis to be interlocked.

A rotary axially movable sleeve 3F is journaled intermediate its ends ina suitable bearing -4.- on the main frame -2- and within this sleeve,and extendintr therethrough is a non-rotatable but axially' movablespindle -5--, around which `the sleeve -3- is adapted torotate.

Slidably mounted upon the lower end of the sleeve -3- is a head -6having a central lengthwise socket --7- opening from its under side andot' greater diameter than that ot thc slctwe forming an inner annularllaiige S Y at the upper end of the head t5- and littiug with an easysliding fit upon the sleeve, tho lower end of the socket being closed bya screw cap or han; dened bearing plate 9A having a central aperturethrough which the lower end of the spindle --5 projects.

A collar lt) is loosely litted with an t easy rotary lit. upon thesleeve 3 `just above the head lt said head and collar being clampedtogether end to end by clamping screws --ll--- which' are passed throughelongated slots 1:'2 -.in the fianges 8 Figs. tl and 5, and screwed intothe under side ot' thc collar --1tl the screws serving to hold the head(3 and collar l0-- against relative endwise movement while the slots--12 permit a limited rotary or rocking movement of thc collarrelatively to said head for a purpose hereinafter described. The upperend of the collar l0 is provided with diametrically opposite slots orrecesses 13 open at the top and inclining downwardly and laterally in adirection opposite to the dii'ection of rotation of the sleeve 3 andheads 6 for receivingr radially projecting roller studs V 1f.1. whichare secured to diametrically opposite sides of the sleeve 3--, as bestseen in Figs. 1, l and 5. The lower end of the sleeve l 3 within thi:socket 7 is enlarged, forming an annular flange 15 which fits with aneasy sliding t within the socket 7 said head 6 being locked to rotatewith the sleeve 3 by means of a key 1(? Which enters a slotted key-wayin the periphery of the flange l5- as best seen in Fig. 5. The verticallength ot' the socket 7 between the flange 8 and bearing plate Q issomewhat greater than the vertical de th of the flange 15 to permit alimited) endwise movement of the head G relatively to the sleeve 3Ywhich latter normally rests upon the flange l5 when the sleeve 3 spindle5- and head their extreme up position, as shown in Fig. 1.

Secured to the lower end of the spindle 5 below the head O and bearingplate Q is a presser head 17 of slightly less diameter than the interiordiameter of the can and having its lower face i made to conform to theshape or contour of the central portion of the head L of the can, theupper side of the head l7 being provided With a ball race 18 for rccciving anti-friction ball bearings 1t) which bear against the under side ofthe bearing,r 1 late lt ot the head Q- whcn said y leads arc in theircxtreme up or down posi tions, said bearings ltl-M serving to rei ducethe l'riclion between the non-rotatable i head 1'T and rotary head Thehead t3- 1s of considerably greater diameter than that ol' thc can andcarries 6 are in,

` 34 as best seen in Fig. 2.

a plurality of upright rock sliaris -tl and 2lwhich are spaced a uniformdistance apart around the axis of the sleeve -3 and spindle 5 and somedistance beyond the periphery of the head iT-- and also some distancebeyond the extreme outer edges of the head of the can. These rock shafts20 and 21 e tend vertically through and beyond theloner and upper facesof the head 6 the rock shafts 20 being provided on their lower and upperends respectively with oppositcly projecting crank arms 2Q- and 23 whilethe rock shafts 2l are also provided vvith similar oppositely projectingcrank arms 2-1 and 25 [he lower crank arms of the rock shafts project inthe direction of rotation from their respective rock sha fte', while theupper crank arms project in the opposite direction, all of said crankarms belli arranged nearly tangential to a circle rawn through the axisof their respective rock shafts.

Mounted on the outer or advance ends of the lower set of crank arms 22-arc crimping rollers 2G and upon the -corresponding ends of the lowercrank arms M are mounted somewhat similar crimping rollers 27 the set ofrollers 2,6 which operate first upon the marginal edges of the can headto partially crimp the same, being provided with annular grooves 28While the rollers 27 (which may be termed the finishing rollers) areprovided with similar but slightly flatter grooves 29 The upper set ofcrank arms Q3- are provided on their rear or trailing ends with rockablecontact pieces 30 adapted to be engaged by tangentially inclined camfaces 32 on diametrically opposite sides of the collar 10 said rockingcontacts l0-- being pivoted to their respective crankarms 23 and areallowed a limited moveA ment against the action of suitable retracting srings 31 for a purpose presently described. The rear or trailing ends ofthe upper crank arms 25 are provided with laterally adjustable contactmembers A -33 which are slidable laterally and adapted to be adjusted bymeans of adjusting screws Y These con tact.- .meinbe s --30 and 33-project inwardly a short distance beyond thc inner sides of theirrespective crank arms Q. and Q5- the contact members --23 be ing engagedbv tangentialiv inclined hearings or cam aces 3.1m which arc alsomounted on diainctrically opposite sides of the collar l0- .'llu` canit'iiccs have a more abrupt. incline and are .somewhat sliorter than thecam tai-es M so as to anse the rollers 2ll to be operated a short periodin advance of the operation of the rollers 27 The precise operation llOof these cams and erim ing rollersI will be more fully explained a iterthe description of the driving mechanism.

Jonrnaled in suitable bearings upon the main supporting frame is ahorizontal driving shaft #361. a main upright shaft 3T-- and acountershaft 458-1 the driving shaft -3(-- being provided with acontinuously rotating loose pulley -3t)- adapted to be connected to anyavailable source of powei not shown, and also adapted to be connected tothe shaft at the will of the operator through the medium of a clutcht0-J which is operated by means ot' a hand lever 41- and connecting rod4Q- as best .seen in Fig. 1.

Loosely mounted upon the lower end of the main shaft H37- is a rotarysleeve -43- which is connected to the driving shaft --tby beveled gears44M and is also connected to the eountershaft a38- by gears 451.

Secured to the upper end of the countershaft -38- is a gear -tG-4 whichtransmits rotary motion to the sleeve 3 through the medium of idle gears47d and a pinion *l8-, the latter being keyed or feathered upon thesleeve 3%. as best .shown in Fig. 1. so as to permit the sleeve to moveendwise relatively to the pinion JIS- This pinion is provided with a hub-19 which is journaled in a suitable bearing in the main frame -2- andis held against upward displacement by a collar -50-.

Feather-ed upon the lower end of the main upright shaft --37- is aclutch collar 51 which is movable into and out of engagement with aclutch section 52d on the lower side of the adjacent gear -44- by meansof a foot lever #555-, Fig. l. Y

lt, is now clear that when the clutch A-LH is thrown into engagementwith the clutch section -52 rotary motion will be transmitted from thedriving shaft 3G- to the main shaft -H-37-, but when said clutch 51" isthrown out of engagement; with said section the main Shaft 37- will beat rest, and at the same time rotary motion is imparted to the drivingshaft F38- and thence through the me diums of the gears -46-, -47- and48M to the sleeve -B-e, whichV in turn rotates the head 6? and partswhich are locked thereto. Theaxial movement of the sleeve 3 andspindle-5- is aecomplished through the medium of grooved earns 54- and 55- andlevers 56- and -57-, the cams 541-4 and -55- being secured to the upperportion of the main shaft #-37- to rot-ate therewith and are onlyrotated whenthe clutch -lwis thrown into engagement with the clutchsecor rollers which ride in their respective i grooved cams -lw andfifi-4. the outer end ot the lever #450m being provided with a lsimilarstud which rides in a grooved collar -t30-- which is secured to thesleeve The outer end of the lever -5T- is connected to a collar -t0-which is secured to the spindle ftlt is now apparent that the sleeve -3Wmay be rotated without moving said sleeve or spindle mit# axially, orsaid sleeve and spindle may be moved axially during such rotation of thesleeve by means of the mechanism pre viously described.

The grooved cams` *5l-n and vCuiai'e so relatively formed and positionedas to cause the spindle 5- to more downwardly to force the presser head1.7 against the head of the underlying can slightly in advance of thedownward movement ot the sleeve 3- and head G to assure the holding ofthe can head in proper position before the rollers Q6-- and 27' arebrought into engagement with the marginal edges of the can head,whereupon the sleeve is depressed by the action of the cam -54- allowingthe head G- to follow downwardly by gravity until the bearing Q- engagesthe roller bearings-194 in which position the rollers -2t5- and -Q7- aredisposed in substantially the same plane butI some distance from themarginal edges of the head of the can, and by continued downwardmovement of the sleeve v3 relatively to the head -G- (which movement ispermitted by the elongated socket the roller studs ltare depressedagainst the inclined sides of the slots d13- thereby rotating the collar-10- and cams 3:2- aud 35 thereon against their respective contactmembers -30 and lthereby rocking the corresponding upper lv crank arms-23 and Q5 outwar y against the action of suitable retracting springs--23- and -25 and effecting a corresponding inward rocking movement ofthe lower crank arms -22 and #24 into contact with the marginal edges ofthe head -bof the can. It is evident. however..A that the rollers -QGHwill be first to engageand partially crimp the ymarginal edges of thehead of the can by reason of the seper incline of the cams -32- and thatthese cams-32- will be moved beyond the contact points of thecorresponding members -30 before the cams 353- complete their operationupon the vcrank arms -25, thereby allowing .the Contact members -30- todrop behind the cams 3Q- and thus'permitting the rollers 2G- to berocked away from the marginal edges of the head of the can afterperforming their work. The cams -35-, however, which are longer than thecams -32- continue to further act u )on the arms 25- to press therollers 2 inwardly and additionally crimp the edges of the head of thecan to give the desired finish and hermeticallv seal the joint, thisoperation heilig accol'nplished during substantially half a revolutionof the main shaft --37-, the remaining part oi' such revolution servingto draw the sleeve --8- and spindle -5Y to their normal up positions,the sleeve 3- being moved upwardly tirst and causes the rollers 14- torido upwardly in the inclined slots l3- for rcstorino the rollers totheir normal out positions. uring the upward movement of the sleeve -3-relatively to the head --6-, the Contact members -30- are forcedbackwardly against the action of the springs `-31- by and out of thepath of the cams *32- toipermit the collar -10- to resume its normalposition, said contact members 30- also assuming a normal startingposition. The members 30- and -3- are normally held in contact withtheir respective cams `32- and -35-. As previously stated the cams -32-are considerably shorter and steeper tangentially than thc cams -35-, soas to cause the corresponding rollers -26- to engage and partially crimpthe marginal ed es of the cap of the can in advance of the nishing oeration by the rollers -27--. That is Whi e the head is rotating, thefree ends of the pawls 3Q-- ride up the inclines and drop in behind thecams -32- and effect the corresponding movement of the rollers -EG` topartially overturn the edges -Ziof the cap under the flan es -aof thecan which action is imme iately followed up by the action of the cams onthe arms 25- to finish the rrimping operation, the cams -35- having aslight vie ding movement under the action of suita le springs -35-. Theupward return movement of the sleeve -3- and spindle 75- to their normalpositions operates the return of the cams 32 and B5-- to their startingpfmitions, the spring 3l-- permitting the pawi -30- to trail over thepoint of the cam 32* and to assume its normal bearing upon the face ofsaid cam.

The o eration of my invention will now be readi y understood uponreference to the foregoing description and accompanying drawings, and itwill be observed that the two important features I wish to protect arefirst, the means for moving the crimpinv rollers inwardly and outwardlytoward and away from the head of the`can, and also means for connectingand disconnecting the driving mechanism from the main shaft -37 whichcontrols the reci rocal movement of the spindle 5" an head -6-.
